MACHINE FOR THE MANUFACTURE OF PRESSED AN D BLOWN GLASSWARE.

To aZZ whom it may concern.-

Be it known that I, CHARLES E. BLUE, a citizen of the United States, residing at Wheeling, in the county of Ohio and State of Vest Virginia, have invented new and useful Improvements in Machines for the Mannfacture of Pressed and Blown Glassware, of which the following is a specification.

My mvention relates to improvements in.

machines for the manufacture of ressedand blown glassware which will be ful y described hereinafter and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved machine, one of the molds being shown in vertical section with the blow-head in operative position. Fig. 2 is a vertical sectional view taken at right angles to Fig. 1, the presserhead and plunger being shown in operative position. Fig. 3 is a top plan view of m Fig. 4 is a detached view showing the blowing attachment operative independent of the plunger. Figs. 5, 6 and 7 are sectional views showing a modification in the construction of the bottom of the press-cavity of the com bined press and blow molds.

Referring now to the drawings, 1 is a suitably supported'at its base, and rotatably supported by this column is a table 2. This table 2 carries a plurality of molds 11, each one of which is provided with a press-cavity 15 and a blow-cavity 14. These molds are vertically centrally divided and 0 en horizontally, being hinged together at t e point 2 and provided with suitable handles 3, by means of which they are opened and closed. Arranged horizontally above and at the side of these molds are horizontal neck-ring-supporting tracks 13, which are supported by suitably arranged vertical standards 13". Supported by and slidable u on these tracks are the neck-rings' 10, w ereby the neclerings which support the pressed blanks are movable from the presscavity of the mold to and over the blowcavity. v .A cylinder 4 is located at the upper end of the column, which is arranged'with' passages d, communicating with opposite ends thereof I in the same manner as 1n the cylinder of'a steam-engine. The outer ends of tliese'passages a communicate with a valve-chamber b, in which is located an oscillating valve (1, which controls th passage of fluid under pressure through t ese passages to opposite Specification of-Letters Patent. lication filed August 23,1902. Serial No. 120,828.

presser-head and ends of the cylinder for the purpose of moving the piston f therein, as is well understood; A handle 6 is carried by the valve (1 f0 trolling it, and this handle projects downward within reach of the operator.

ger-rod 6 is attached to the piston plunger 8 is carried by the lower end thereof and is adapted to -enter the the mold that may be located 'thereunder. Anarm 2.0 piston-rod, and the outer end of this arm supports and carries a suitable blow-head 23. A tube 21 communicates with the blowhead, and a flexible tube 22 is connected with the tube 21, permitting the blow-head to be raised and lowered. Since'the blow-head is connected with the plunger-rod 6 by the arm 20, as before explained, it will be understood that the blow-head is moved up and down in unison w1th the plunger.

- By reference to Fig. 3 it will be noted that preferably five molds are used and that as, the table 2 is rotated these molds will successivel occu y the chargin ressin "blo iivingfi "diseharging, ind coolin g positions designated in this view.

In Fig. 2 the means for locking the table at the proper points for operation is plainly illustrated, and consists of a vertically spring-actuated rod 16, having its upper end properly sha ed to enter cavities in the under side of t e table. This rod slides in a bfacket l8 and is operated by a suitable hand e 17.

As previously stated, the blow-head in Fig. 1 is shown connected with the plungerrod and moved thereby. ever, the blow-head is shown separate from the plunger and slides vertically in a horizontal bracket projecting from the upper end of the column 1. Aspring 24 serves to hold the blow-head 23 normally upward, and it is moved down to the blowing position against the tension of this s ring through the medium of a horizontally-projecting pivoted handle 25.

If desired, the press-cavities may have a movable bottom 71, as shown in Figs. 5, 6, and 7, which is for the purpose of preventing the formation of a seam across the bottom of the finished article.

handle j, which is provided with a cam-slot is, through which passes a pinm.

In operation the neck-ring is opened at the discharging-point and molten glass is placed Patented A u g 7, 1906.

In this instance the bottom is actuated through the medium of a sliding.

Aplunf, and a press-cavity of Fig. 4', howfinished article in the blow-cavity.

in the press-cavity of each mold and the mold is closed when at the charging-point, Fig. 3,

and the table 2 is rotated to carry the charged mold to the pressing-point. The plunger is then caused to move therein through the movement of the handle e for' the purpose of forming a pressed blank to be blown into Tv e mold is then opened and the pressed blank is supported by the neck-ring, and the neckring is moved on its supporting-track i3 until the blank is positioned within the blow-eavity, after which the mold'is closed, glass is dropped in the press-mold at the chargingpoint, and the table rotated one-fifth of a re"- olution. Another pressing operation is performed and at the same time a blowing operation is efiected. As the table is moved around, each mold assumes the several positions indicated in Fig. 3, where the charging,

pressing, blowing, discharging, and cooling is effected.

From this description it will be understood that the table 2 is, in effect, generically an endless carrienwhich is provided with a plurality of molds, each mold having a press and a blow cavity and preferably each mold provided with a neck-ring-supporting track upon which the neck-ring is adapted tobe moved from one cavity of the mold to the other.

Stops will be provided on the neck-ring track for the purpose of limiting the move ment of the neck-ring and insuring the prop er centralizing of the neck-ring in respect to the press and blow cavities.

Attention is directed to the interior forma tion of the; ress-cavity, it being enlarged centrally wit its mouth or inlet relatively smaller. This construction enables me to get more glass in a certain-sized top opening than is possible where the cavity tapers gradually from top to bottom in the usual manner. a

In Fig; 1 the blow-headis connected with l the presser-head and is automatically worked,

as before stated, and in Fig. 2 I show another form of automatic connection. This consists of ale'ver 4.0, which has its outer end pivotally connected with the spring-actuated rod 16, and this red is adapted to' be operated by either the hand-lever 17 or the foot-lever 43. p A rod 41 has its lower end pivo tally connected with the lever 40 and its upper end pivotally'connected with the inner end. of an intermediately-pivoted lever 42, located at the 11 per end of the column 1. The outer end o the said lever 42 is adapted to actuate the tube 21, which carries the hlow-head,'so that when the spring-actuated rod is permitted to engage the table after it has been moved to carr the molds to proper position.
